Triaxial orbit based galaxy models with an application to the (apparent) decoupled core galaxy NGC 4365
R. C. E. van den Bosch, G. van de Ven, E. K. Verolme +2
We present a flexible and efficient method to construct triaxial dynamical models of galaxies with a central black hole, using Schwarzschild's orbital superposition approach. Our m…
The shape of the dark matter halo in the early-type galaxy NGC 2974
Anne-Marie Weijmans, Davor Krajnovic, Glenn van de Ven +3
We present HI observations of the elliptical galaxy NGC 2974, obtained with the Very Large Array. These observations reveal that the previously detected HI disc in this galaxy (Kim…
Fast and Slow Rotators: The build-up of the Red Sequence
Eric Emsellem, Michele Cappellari, Davor Krajnovic +11
Using the unique dataset obtained within the course of the SAURON project, a radically new view of the structure, dynamics and stellar populations of early-type galaxies has emerge…
Recent Star Formation in Nearby Early-type Galaxies
M. Sarzi, R. Bacon, M. Cappellari +9
Motivated by recent progress in the study of early-type galaxies owing to technological advances, the launch of new space telescopes and large ground-based surveys, we attempt a sh…
Towards a new classification of early-type galaxies: an integral-field view
J. Falcón-Barroso, R. Bacon, M. Cappellari +9
In this proceeding we make use of the two-dimensional stellar kinematics of a representative sample of E and S0 galaxies obtained with the SAURON integral-field spectrograph to rev…
Absorption line-strengths of 18 late-type spiral galaxies observed with SAURON
Katia Ganda, Reynier F. Peletier, Richard M. McDermid +10
We present absorption line-strength maps for a sample of 18 Sb-Sd galaxies observed using the integral-field spectrograph SAURON. The SAURON spectral range allows the measurement o…
The SAURON project -- IX. A kinematic classification for early-type galaxies
Eric Emsellem, Michele Cappellari, Davor Krajnovic +10
2D stellar kinematics of 48 representative E and S0 galaxies obtained with the SAURON IFS reveal that early-type galaxies appear in two broad flavours, depending on whether they ex…
The Nature of Galactic Bulges from SAURON Absorption Line Strength Maps
Reynier F. Peletier, Jesus Falcon-Barroso, Katia Ganda +10
We discuss SAURON absorption line strength maps of a sample of 24 early-type spirals, mostly Sa. From the Lick indices H, Mg b and Fe 5015 we derive SSP-ages and metallicities.…
